(1) Climatic conditions. Storage facilities for pesticides should be cool,
dry, and well ventilated. The reasons for maintaining such conditions are preservation
of materials and safety. Chemicals deteriorate more rapidly under conditions of warmth,
humidity, and exposure to sunlight. Adequate lighting should be provided to prevent
errors in reading labels, but materials should be protected from continuous exposure to
sunlight. Ventilation is important in the interest of safety. The collection of fumes from a
leaky container could present a hazard both from the standpoint of inhalation and from
the possibility of explosion.
(2) No smoking. "No Smoking" signs should be posted at prominent
points in the storage area, and compliance should be vigorously enforced. Many
pesticides are highly flammable.
(3) Containers. Pesticide containers should be segregated according to
their containers, stored away from other chemicals, and stored under a sign indicating
the name of the formulation. This precaution is not only to preclude the possibility of a
reaction should two chemically reactive agents come in contact with one another, but
also to prevent errors in selecting or issuing pesticides. Most of the original containers
designed for insecticides are adequate for prolonged storage. However, stocks should
be inspected frequently for detection of any leaks or unsafe storage conditions. Glass
containers are excellent substitutes for faulty metal containers. Metal containers not
specially treated may be unsuitable for prolonged storage of some pesticides. Lindane,
which has a corrosive action on some metals, is an example. Many of the emulsion
concentrates and dilute oil-based insecticides are flammable. Spark-proof lighting
fixtures must be installed and ignition hazards must be eliminated in closed storage
(4) Labels. All containers must be plainly labeled and kept closed. Never
use empty food or drink containers to mix, pour, measure, or store any pesticide.
b. Disposal. Disposal of unwanted pesticides is one of the most difficult
problems facing pest control personnel today. Because of the strict environmental
controls established by the Environmental Protection Agency, previously authorized
methods of disposal are no longer permitted. All methods of destruction are closely
controlled because of environmental considerations -- air, water, and soil pollution. Until
current Army regulations and Government directives (which are under revision at the
time of this writing) have been revised, the following guidelines apply.
(1) In every possible instance, use the pesticide for its intended use.
Dispose of the container in accordance with instructions obtained through command
channels. Never use empty pesticide containers for any other purpose.
(2) Excess pesticides that are still in serviceable condition and in
serviceable containers should be turned in through normal supply channels. If they are
not acceptable and cannot be used, they must be disposed of as directed through
